VALVE.

fr'EEGIFIGATIGN forming part of Letters Patent No. 695,333, dated March 11, 1902.

Application filed May 31,1901. Serial No. 62,531. (No model.)

To all whom it nuty concern.-

Be it known that I, NICHOLAS OBoLENsKii, a citizen of the United States of America, and a resident of Hermitage, in the county of lVyoming and State of New York, have invented a new and Improved Valve, of which the following is a full, clear, and exact description.

The invention relates to check-valves; and its object is to provide a new and improved valve which is simple and durable in construction, very effective in operation, not liable to get out of order, and arranged to permit convenient access to the working parts at any time and to allow quick replacement of worn-out parts with new ones.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then point ed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the views.

Figure 1 is a sectional side elevation of the improvement, and Fig. 2 is a sectional plan view of the same on the line 2 2 in Fig. 1.

The valve consists, essentially, of a valvebody A, having a continuous passage A, ter lninating at one end in an inlet A and at the other end in an outlet A and on one side of the valve-body is formed an extension A, containing a cage consisting of bars B, secured at their inner ends on a valve seat B for the valve 0, the outer ends of the bars'B being engaged by a valve-seat B similar to the valve-seat B. The cage thus formed is provided at its inner and outer ends with valveseats to permit of placing either end of the cage in the extension A, so as to bring the corresponding valve -seat B or B into the continuous passage A, as is plainly illustrated in the drawings.

On the bars B and approximately midway between the valve-seats B B is arranged a stop D for limiting the opening movement of the valve 0, which is preferably in the shape of a ball; but I do not limit myself to the particular form of the valve shown. The stop D is set in recesses out in the bars B to permit of turning the cap around when the cage is to be reversed and the outer valve-seat is moved into the continuous passage A. In order to hold the cage in position on the extension A, the inner valve-seat abuts against an annular shoulder A around the continuous passage, and the outer valve-seat is engaged by a cap E, screwing in the outer end of the extension A. A gasket F may be placed in a recess on the annular shoulder A to receive the inner valve-seat and form a very firm joint between the valve-seat and the'shoulder to prevent leakage when the valve 0 is in position on its seat.

From the foregoing it is evident that upon unscrewing the cap E the cage, with the Valve 0 and stop D, can be readily removed from the extension A for cleaning or other purposes or for reversingthe cage and bringing the valve-seat B into an innermost position. Thus ready access is had to the working parts of the valve, and in case both seats B B are completely worn out then they can be replaced by other seats attached to the bars B. The valve is then again as good as new.

In the passage A near the inlet A is arranged a drain-cock G, and a plug H is also secured on the valve-body A to permit of cleaning the inlet portion whenever desired.

Having thus fully described my invention, I claim as new and desire to secure byLetters Patent 1. A check-valve having a valve-body, provided with a continuous passage, a cage removably held in said valve-body and having a valve-seat extending in said passage, a valve proper movable in said cage and adapted to be seated on said valve-seat and a stop mounted in the cage, as set forth.

2. A check-valve having a valve-body provided with a continuous passage, a cage removably and reversibly held in. said valvebody and provided at both ends with valveseats, of which the inner valve-seat extends in the passage, a valve proper movable in said cage and adapted to be seated on the inner valve-seat, and a stop carried by said cage seats, of which the inner valve-seat extends in the passage, a valve proper movable in said cage and adapted to be seated on the inner valve-seat, and a stop carried by said cage, for limiting the opening movement of said valve, said stop being reversibly held in said cage, as set forth.

4. A check-valve having a valve-body provided with an extension between theinlet and the outlet and opening into the continuous passage of the valve-body, a cage reniovably and reversibly held in said extension and provided at each end with a valve-seat, of which the inner valve-seat extends into said passage, and a valve proper in said cage and seated on the inner valve-seat, as set forth.

5. A check-valve having a valve-body provided With an extension between the inlet and the outlet and opening into the continuous passage of the valve-body, a cage removably and reversibly held in said extension and provided at each end with a valve-seat, of which the inner valvo-seat extends into said passage, a valve proper in said cage and seated on the inner valve-seat, and a stop reversibly held in said cage, as set forth.

6. A check-valve having a valve-body provided with an extension between the inlet and the outlet and opening into the continuous passage of the valve-body, a cage relnovably and reversibly held in said extension and provided at each end With a valve-seat, of which the inner valve-seat extends into said passage, a valve proper in said cage and seated on the inner valve-seat, and a screw-cap screwing on the outer end of the extension and engaging the outer valve seat, to hold the cage in place, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
